Deployment Exercise (DEPEX): An exercise which provides training for individual soldiers, units, and support agencies in the tasks and procedures for deploying from home stations or installations to potential areas of hostilities.

Doctrine: Fundamental principles by which military forces guide their actions in support of objectives. It is authoritative but requires judgment in application.

Field Training Exercise (FTX): A high-cost, high-overhead exercise conducted under simulated combat conditions in the field. It exercises command and control of all echelons in battle functions against actual or simulated opposing forces.

Fire Coordination Exercise (FCX): A medium-cost, reduced-scale exercise that can be conducted at platoon, company/team, or battalion/task force level. It exercises command and control skills through the integration of all organic weapon systems, as well as indirect and supporting fires. Weapon densities may be reduced for participating units, and subcaliber devices substituted for service ammunition.

Fire Support Battlefield Operating System: The collective and coordinated use of target acquisition data, indirect fire weapons, armed aircraft (less attack helicopters), and other lethal and nonlethal means against ground targets in support of maneuver force operations.

Force Integration: The process of incorporating new doctrine, equipment, and force structure into an organization while simultaneously sustaining the highest possible levels of combat readiness.

Inactive Duty Training (IDT): Authorized training performed by a Reserve Component member not on active duty or active duty for training, and consisting of regularly scheduled unit training assemblies, additional training assemblies, or equivalent training periods.

Intelligence Battlefield Operating System: The collection of functions that generate knowledge of the enemy, weather, and geographical features required by a commander in planning and conducting combat operations.

Logistics Exercise (LOGEX): An exercise which concentrates on training tasks associated with the combat service support battlefield operating system.

Maneuver Battlefield Operating System: The employment of forces on the battlefield through movement and direct fires, in combination with fire support, to achieve a position of advantage in respect to enemy ground forces in order to accomplish the mission.

Map Exercise (MAPEX): A low-cost, low-overhead training exercise that portrays military situations on maps and overlays that may be supplemented with terrain models and sand tables. It enables commanders to train their staffs in performing essential integrating and -control functions under simulated wartime conditions.

Mission: The primary task assigned to an individual, unit, or force. It usually contains the elements of who, what, when, where, and the reasons therefore, but seldom specifies how.

Mission Essential Task: A collective task in which an organization must be proficient to accomplish an appropriate portion of its wartime mission(s).

Mission Essential Task List (METL): A compilation of collective mission essential tasks which must be successfully performed if an organization is to accomplish its wartime mission(s).

Mission Training Plan (MTP): Descriptive training document which provides units a clear description of "what" and "how" to train to achieve wartime mission proficiency. MTPs elaborate on wartime missions in terms of comprehensive training and evaluation outlines, and provide exercise concepts and related training management aids to assist field commanders in the planning and execution of effective unit training.

Mobility and Survivability Battlefield Operating System: The capability of the force permitting freedom of movement relative to the enemy while retaining the ability to fulfill its primary mission. The Mobility and Survivability BOS also include those measures that the force takes to remain viable and functional by protection from the effects of enemy weapons systems and natural occurrences.

Multiechelon Training: A training technique to simultaneously train more than one echelon on different tasks.

Operating Tempo (OPTEMPO): The annual operating miles or hours for the major equipment system in a battalion-level or equivalent organization. OPTEMPO is used by commanders to forecast and allocate funds for fuel and repair parts for training events and programs.
